New info for SRAM 2009 -
The crankset gets an important upgrade: The axle is bigger, it is now 30mm of diameter instead of 24mm. The new BB 30 Standard. * Stiffer * The weight is reduced * Q-Factor is reduced * Bearings are larger, meaning stiffer and more durable as well.
There are two new cassettes offered beside the current 11/23 and 11/26: - 11/25: 11, 12, 13, 14, 15, 17, 19, 21, 23, 25 - 11/28: 11, 12, 13, 14, 15, 17, 19, 22, 25, 28
SRAM RED TT
SRAM offers some new time trial components.
- A PowerGlide technology chainring: * 55, 54 and 42 teeth * Grey tungstene finish to improve resistance * Aero chainring which increase the stiffness too - The 500TT shift levers have a new a red touch * cheaper than the carbon version * the rear shift lever is indexed, the front one is operated on a friction mode * 154g per set - Aero brake levers, the 500TT: * red color * 115g per set, which is 16g heavier than the carbon version
Certainly the most reworked for 2009. It uses a lot of the systems featured on the high range groupsets. This is probably a best-seller if the price isn't too high. - Black finish - Carbon levers (320g, 20g saved) * System Zero-Loss for the front derailleur (read further explanations above) * The brake and shifter cable housings can run along either side of the handlebar * Reach adjustment * Wider aluminum shifter paddle - Aluminum hollow cranks, OCT technology (open core) * 40g are shaved off the previous version * Available in compact (110mm), and standard (130mm) * Cranks length from 165 -180mm
The SRAM Force groupset get several upgrades from the high range Red groupset.
Only the levers are modified:
* They are longer
* The shifter paddle is reworked, it is widened
* The brake and shifter cable housings can run along either side of the handlebar
* Reach adjustment
* The front derailleur with Zero-Loss technology which engages front shift immediately.
